Definitions

  • the invention relates to a channel element for forming a drainage channel which is laid in the floor and embedded therein, according to the preamble of claim 1.
  • Such channel elements are used for drainage, for example, from garage entrances, parking spaces or underground garages.
  • a channel element with a plurality of webs arranged in the longitudinal direction between the side walls of the channel element is known, the height of the webs being less than the height of the side walls. So that motor vehicles driving over them do not destroy such drainage channels in a short time, these channel elements must be dimensionally stable and securely anchored in the subsurface.
  • Conventional drainage channels are therefore made of relatively thick-walled concrete.
  • the drainage channel is usually composed of several channel elements arranged one behind the other.
  • Such drainage channels made of concrete are laid in such a way that first a trench is dug, which is provided with a sole made of lean concrete.
  • the various channel elements are then lined up on this sole, after which the trench for embedding the channel elements on all sides is filled with concrete.
  • To adjust the installation height of the channel elements is from the US 4,993,877 A an adjustment device is known with which the channel elements can be fixed at the desired height in a trench.
  • Such channel elements made of concrete are very heavy, so that handling when laying and embedding in the subsurface is relatively difficult. For example, a 1 meter long duct element made of concrete can be laid as wide as possible. Due to the relatively high impact sensitivity of the channel elements made of concrete, the transport, which can generally only be carried out with a truck anyway, is also associated with an increased risk of damage. Furthermore, the brittleness of the channel elements made of concrete also results in storage problems. Such channel elements must be transported and stored very carefully, so that the channel elements directly lying on top of one another and abutting are avoided as far as possible.
  • a generic gutter element which is made of plastic instead of concrete and has several webs for forming drainage channels.
  • the weight of the channel element can be significantly reduced by using plastic in the production of the channel element.
  • the DE 82 20 949 U1 also discloses a generic channel element made of plastic.
  • the channel element In order to be able to drain the water, for example rainwater or dripping water, the channel element forms a U-shaped channel, which consists of a horizontal base section and two side walls.
  • a metallic cover grille is attached to the top of the channel element, which is permeable to water and at the same time forms an easily accessible road surface.
  • a drainage channel with grating is known.
  • a disadvantage of these metallic cover gratings is that when cleaning the channel element, for example to remove leaves and other dirt particles from the U-shaped channel, the cover grate must be removed in each case.
  • the costs for the channel element are significantly increased by the additional cover grate.
  • care must also be taken to ensure that the individual cover grids are not separated from the channel elements assigned to them.
  • the channel element according to the invention is based on the basic idea that at least one support web is formed on the bottom section between the side walls and extends vertically upwards.
  • the upper end of the support web runs essentially at the same height as the upper end of the two side walls. Due to the support web between the two side walls, the free distance between the side walls is halved, divided into three, divided into three, depending on the number of support webs Roadway are formed at the top of the channel element. Because due to the diameter of vehicle tires, a free distance between the side walls and the individual support webs of, for example, only 10 to 20 mm can be passed without problems.
  • the U-shaped channel of the channel element is divided into a plurality of U-shaped subchannels by the support webs attached to the top of the base section, the free distance between the individual subchannels being correspondingly smaller and thus being able to be passed over without problems.
  • one or more stiffening ribs are formed on the underside of the base section.
  • a further special drain gutter element at the end of a water drainage channel formed from several gutter elements, which serves exclusively as a water inlet spigot. The picking, storage and transportation of such special water inlet boxes represents a high logistical and therefore costly expense.
  • a water drainage element is already molded into the channel element according to the invention.
  • the respective channel element is not intended to form a water drain, this is already formed on the water drain element genetically sealed.
  • the water drainage element itself is initially made impermeable to water.
  • the water drainage element has predetermined bore markings.
  • the user can break through the water impermeability of the water drain by making appropriate bores on the predetermined bore markings and in this way can easily realize the desired water drainage element by drilling the bores only on the construction site.
  • one or more stiffening ribs are formed on the underside of the base section.
  • the number of support webs attached between the two side walls can ultimately be optionally adapted to the respective application, the free distance between the side walls and the support webs not exceeding a certain dimension in order to ensure that the top of the channel element can be driven over.
  • the side walls and the four support webs result in five sub-channels with a width in the range between 10 and 15 mm. This width of the individual subchannels can then be easily passed over by a vehicle even without a covering grille being attached.
  • the material transitions between the supporting web on the one hand and the base section on the other hand are rounded off with transition radii.
  • the channel elements according to the invention are often concreted into road surfaces. This means that the gutter elements are first installed at the desired height on the construction site and then cast in concrete. The concrete, which has not yet hardened, is then smoothed on the upper side of the channel elements, so that a smooth concrete road surface adjoins it forms at the height of the upper end of the support webs or the side walls.
  • This application of the initially liquid concrete when pouring over the channel elements and in particular the smoothing of the concrete to form the concrete road surface is considerably simplified if a removable cover element is arranged on the top of the channel element, with which the individual channels formed between the support webs and the side walls from above be closed.
  • the cover element As a result, an undesired penetration of the concrete into the individual channels of the channel element is avoided by the cover element during the pouring of the channel elements into the concrete. As soon as the concrete has completely hardened, the cover elements can be removed and the channel elements can thus be used for water drainage.
  • the manner in which the cover elements are fixed on the top of the channel element is fundamentally arbitrary. This can be implemented in a particularly simple manner by means of clamping elements which are arranged on the underside of the cover element and come into engagement in a fixing manner on the support webs or on the side walls.
  • the cover element can be produced from sheet metal material in a particularly simple and cost-effective manner.
  • the clamping elements for fixing the cover element can be easily integrated into the cover element by appropriately cutting out and bending the sheet metal material.
  • the channel elements In order to enable the channel element to be concreted in, the channel elements must be fitted with suitable assembly means before the concrete is applied be pre-fixed at the desired height.
  • at least one stand element can be attached to the underside of the base section.
  • the stand element itself can then be attached to the top of the respective structure, for example the raw ceiling of an underground car park.
  • a predetermined installation height of the channel element is then secured above the structure by the stand element itself.
  • the top of the channel elements defines the height of the road surface that will be formed later when the roadway is concreted.
  • the stand element comprises an adjusting device with which the installation height of the channel element can be adjusted above the structure when the column element is attached between the structure and the channel element.
  • the adjusting device can be designed in the manner of an adjusting thread in a particularly simple and inexpensive manner.
  • the installation height of the channel element can then be easily varied and fixed by attaching and adjusting adjusting nuts.
  • the plastic from which the channel elements are made is basically arbitrary. A particularly high stability and durability results if the channel elements are made of a thermoset. In order to achieve a particularly high mechanical strength, it is advantageous if reinforcing fibers, in particular glass fibers, are embedded in the plastic from which the channel elements are formed.
  • the channel elements according to the invention can be particularly simple and can be produced inexpensively and mechanically highly stable from prefabricated thermoset prepregs. For this purpose, the thermoset prepregs, which already contain the desired amount of glass fibers, are placed in a suitable press mold and cured there under heat after the desired geometry of the channel element has been formed.
  • Fig. 1 shows a channel element 01, which is made of a glass fiber reinforced thermoset in a perspective view from above.
  • a channel element 01 which is made of a glass fiber reinforced thermoset in a perspective view from above.
  • several channel elements 01 can be arranged one behind the other in a road surface in order to allow surface water to drain off.
  • Fig. 2 shows the channel element 01 in cross section along the section line II (see Fig. 4 ).
  • the channel element 01 comprises a bottom section 02 and two side walls 03 and 04. Between the side walls 03 and 04, four support webs 05 are integrally formed on the top of the bottom section 02.
  • the upper end 06 of the support webs 05 runs at the height of the upper end 07 or 08 of the two side walls 03 and 04.
  • the arrangement of the support elements 05 between the two side walls 03 and 04 reduces the width of the partial channels 09 formed by the side walls 03 and 04 and the support elements 05 to such an extent that the partial channels 09 are passed over by rolling on the upper ends 06, 07 and 08 is easily possible.
  • stiffening ribs 10 and 11 are integrally formed on the underside of the bottom section 02. Transition radii 13 are provided at the material transition between the support webs 05 and the base section 02 in order to simplify the cleaning of the partial channels 09 and to increase the mechanical stability of the support webs 05.
  • FIG. 3 and 4 show the channel element 01 in a side view or in a view from above.
  • a water drainage element 12 molded into the channel element 01, to which a water drainage connection or a water drainage pipe can be connected.
  • the water drainage element 12 is initially made impermeable to water and thus contains no water-permeable recesses. Instead, there are target bore markings in the water drainage element (in 3 and 4 not shown) molded in, in order to make it easier for the user to make corresponding bores in the area of the water drainage element in the event that a channel element is to be equipped with a water drainage element. If the user has drilled through the water drainage element 12 at the predetermined bore markings, it is then water-permeable, so that the water guided in the subchannels 09 can flow downwards.
  • Fig. 5 shows the channel element 01 when attached to two stand elements 14 and 15.
  • a sheet metal web 16 which projects laterally on the channel element 01, is first attached from the underside of the channel element 01.
  • two through bores are provided, which are penetrated by threaded rods 17.
  • the groove element 01 can then be fixed on the stand elements 14 and 15 by means of fixing nuts 20.
  • a cover element 21 is attached, with which the partial channels 09 of the channel element 01 are closed from above in order to prevent liquid concrete from penetrating into the partial channels 09 during pouring with concrete.
  • Fig. 6 shows the channel element 01, the stand element 14 and the cover element 21 when arranged on the bare ceiling 22 of an underground car park in a side view.
  • Fig. 7 shows the channel element 01, the stand element 14 and the cover element 21 after casting with concrete 23 to form a road surface 24 in cross section. It can be seen that the upper ends 06, 07 and 08 of the supporting webs 05 and the side walls 03 and 04 lie exactly at the level of the road surface 24 formed by the concrete mass 23 and can therefore be easily run over by vehicle wheels. The penetration is through the cover member 21 of liquid concrete mass 23, while smoothing the road surface 24, easily avoided.
  • Clamping elements 25 are provided on the underside of the cover element 21, with which the cover element 21 can be fixed on the channel element 01. Clamping elements 25 are realized by cutting out and bending down the sheet metal material from which the cover element 21 is made.
  • Fig. 8 shows the final state after installation of the channel element 01 in the concrete pavement surface 24. After removing the cover element 21, the partial channels 09 are open at the top and can easily drain off the surface water accumulating on the pavement surface 24 and thus drain the pavement surface 24 in the desired manner .
